When I am on my Windows XP box I can access our SharePoint Document Library via the UNC path just fine. \\server\DocLib, and it comes right up. However on my 2000 and 2003 Servers if I type in that path at the run command it says it can't find it. I can still access the web version just fine though, but I need access to access it this way. On all three boxes I am logged in using the same account, and on all three I have local admin privelages, though i was able to access it just fine without these on my local box before all this.
